I've seen the postings for the official JD CUT Ballast Calculator, but noticed that the 1026R is not listed. I've tried to find it on the JD website but no luck either.

Any way I can update it or find an updated one?

Unfortunately I think you're going to have to wait for Deere to update that information. If it is something you have in mind to ballast your machine you probably can use the 2305 data and get pretty close to what you need.
